Technical Field

[0001] This application relates to the field of vehicle equipment technology, and in particular to a driver monitoring system and a vehicle. Background Technology

[0002] With the increasing intelligence of automobiles, driver monitoring systems have become widely used. A driver monitoring system generally consists of two parts: a camera and a controller. The camera collects video information and transmits it to the controller, which then makes algorithmic decisions and issues corresponding instructions to the actuators.

[0003] Existing driver monitoring systems typically integrate cameras and controllers into a single unit. These cameras are prone to overheating, and accidental contact by people inside the vehicle can easily cause injury. Utility Model Content

[0004] The driver monitoring system and vehicle provided in this application embodiment keep the lens assembly and control assembly far apart, reducing the probability of heat generated by the control assembly being transferred to the lens assembly, thereby reducing the temperature of the lens assembly and consequently reducing the probability of the driver accidentally touching the lens assembly and getting burned while driving.

[0005] In a first aspect, embodiments of this application provide a driver monitoring system, including:

[0006] A lens assembly, comprising an interconnected lens body and a first circuit board;

[0007] The control component is separately disposed from the lens assembly. The lens assembly includes a first housing, a control circuit board connected to the first housing, and a plurality of heat sinks. The control circuit board is electrically connected to the first circuit board and is located inside the first housing. The plurality of heat sinks are all connected to the outer surface of the first housing.

[0008] In this embodiment, multiple heat dissipation components protrude from the first housing along a first direction and form a first heat dissipation channel extending along a second direction and a second heat dissipation channel extending along a third direction and communicating with the first heat dissipation channel on the outer surface of the first housing. The first direction, the second direction and the third direction intersect each other.

[0009] In some embodiments, the control component includes a first thermal conductive element connected to the side of the first housing facing the control circuit board, the side of the first thermal conductive element away from the first housing abutting against the control circuit board, and the projection of the first thermal conductive element in a first direction being inside the projection of the plurality of heat sinks in the first direction.

[0010] In some embodiments, a partition rib is provided protruding from the interior of the first housing along the first direction, the partition rib dividing the interior of the first housing into a first cavity and a second cavity arranged side by side along a fourth direction, the fourth direction intersecting the first direction;

[0011] The control circuit board includes a main body and a connecting part that are connected to each other. The projection of the main body in the first direction is located in the first cavity, and the projection of the connecting part in the first direction is located in the second cavity.

[0012] In some embodiments, the lens assembly includes a lens bracket, the lens body is connected to the lens bracket and extends along a fifth direction to one side of the lens bracket, and the first circuit board is connected to the side of the lens bracket opposite to the lens body in the fifth direction.

[0013] In some embodiments, the lens bracket is provided with a connector, both ends of the connector protruding from the lens bracket along the fifth direction, and the connector is provided with a connecting hole through the fifth direction. Part of the lens body is located inside the connecting hole, and one end of the lens body passes through the connecting hole and is connected to the first circuit board.

[0014] In some embodiments, the connector has an elastic pad at one end facing the first circuit board in the fifth direction, the elastic pad is connected to the connector, and the side of the elastic pad facing away from the connector abuts against the first circuit board.

[0015] In some embodiments, the lens assembly further includes a light source connected to the lens bracket and located on the same side of the lens bracket in the fifth direction as the lens body, and the light source is disposed on one side of the lens body along a sixth direction, the fifth direction intersecting the sixth direction.

[0016] In some embodiments, the lens assembly further includes a light-shielding member connected to the lens bracket and located on the side of the lens body facing away from the lens bracket in the fifth direction;

[0017] The light-shielding member is provided with a light-transmitting area, and the projection of part of the light-transmitting area in the fifth direction coincides with the projection of the lens body in the fifth direction, and the projection of part of the light-transmitting area in the fifth direction coincides with the projection of the light source in the first direction.

[0018] In some embodiments, the lens assembly includes a second circuit board, the light source is disposed on the second circuit board, the lens bracket has a first protrusion protruding along the fifth direction, and the second circuit board is connected to the first protrusion;

[0019] The lens bracket is provided with a second heat-conducting component protruding along the fifth direction. The side of the second heat-conducting component away from the lens bracket abuts against the second circuit board. The projection of the second heat-conducting component in the fifth direction overlaps with the projection of the light source in the fifth direction.

[0020] Secondly, embodiments of this application provide a vehicle including the aforementioned driver monitoring system.

[0021] According to the driver monitoring system and vehicle provided in this application, the lens assembly and control assembly are separately arranged, keeping them far apart. This reduces the probability of heat generated by the control assembly being transferred to the lens assembly, thereby lowering the lens assembly's temperature and consequently reducing the probability of the driver accidentally touching the lens assembly and suffering burns. Simultaneously, a heat sink is provided on the outer surface of the first housing to dissipate heat generated by the control circuit board, reducing the temperature of the control assembly during operation. Specifically, multiple heat sinks protrude from the first housing along a first direction, forming a first heat dissipation channel extending along a second direction and a second heat dissipation channel extending along a third direction on the outer surface of the first housing. The first and second heat dissipation channels are interconnected. When airflow passes through the first housing, because the heat sinks protrude from the first housing along the first direction, the airflow can directly contact the heat sinks. After contact with the heat sinks, the airflow will circulate along the first and second heat dissipation channels formed by the multiple heat sinks on the outer surface of the first housing. By positioning the multiple heat sinks on the first housing and guiding the path of the airflow through the heat sinks, the heat dissipation efficiency of the control assembly can be improved. Furthermore, the first and second heat dissipation channels are interconnected, which expands the airflow range when the air passes through the heat sink, thereby improving the heat dissipation efficiency of the control components and reducing the temperature of the control components during operation.

[0035] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0037] Driver monitoring systems are used to monitor driver behavior, aiming to detect driver inattention, fatigue, drowsiness, and other conditions that render the driver unable to drive. With the increasing intelligence of automobiles and the growing emphasis on active safety systems, the application of driver monitoring systems is becoming more widespread. A driver monitoring system generally consists of two parts: a camera and a controller. The camera collects video information and transmits it to the controller, which then uses algorithms to make decisions and issue corresponding instructions to the actuators.

[0038] The camera and controller of existing driver monitoring systems are usually integrated into one unit. The heat generated by the controller can easily be transferred to the camera, causing the camera lens to heat up. If people in the vehicle accidentally touch the camera, it can easily cause injury.

[0039] In view of this, firstly, please refer to Figures 1 to 3 This application provides a driver monitoring system, which includes a lens assembly 10 and a control assembly 20. The lens assembly 10 includes a lens body 11 and a first circuit board 12 connected to each other. The control assembly 20 is separately disposed from the lens assembly 10. The lens assembly 10 includes a first housing 21, a control circuit board 22 connected to the first housing 21, and a plurality of heat sinks 23. The control circuit board 22 is electrically connected to the first circuit board 12 and is located inside the first housing 21. The plurality of heat sinks 23 are all connected to the outer surface of the first housing 21. The plurality of heat sinks 23 protrude from the first housing 21 along a first direction X. The plurality of heat sinks 23 form a first heat dissipation channel 231 extending along a second direction Y and a second heat dissipation channel 232 extending along a third direction Z and communicating with the first heat dissipation channel 231 on the outer surface of the first housing 21. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0040] The driver monitoring system provided in this application includes a lens assembly 10 for capturing images and a control component 20 for analyzing the image data acquired by the lens assembly 10. The lens assembly 10 and the control component 20 are separately configured and electrically connected using a connecting harness 30. This arrangement keeps the lens assembly 10 and the control component 20 far apart, reducing the probability of heat generated by the control component 20 being transferred to the lens assembly 10, thereby lowering the temperature of the lens assembly 10 and consequently reducing the probability of the driver accidentally touching the lens assembly 10 and suffering burns. The lens assembly 10 is the combined structure for acquiring images in the driver monitoring system, and the control component 20 is the combined structure for analyzing and processing image data in the driver control system.

[0041] Furthermore, by designing the lens assembly 10 and the control assembly 20 as separate units, they can be installed independently, reducing the space required for the entire driver monitoring system and simplifying their installation. Moreover, separating the lens assembly 10 and control assembly 20, compared to an integrated structure, allows for individual installation of the control assembly 20. This reduces the limitations imposed by installation space constraints on the control assembly 20, enabling the control circuit board 22 to be enlarged to accommodate more functional components, thereby improving its performance and stability during operation.

[0042] The lens assembly 10 includes a lens body 11 and a first circuit board 12 connected to each other. The lens body 11 faces the driver, and the first circuit board 12 is provided with a chip that matches the lens body 11 to process the image acquired by the lens body 11.

[0043] The control component 20 includes a first housing 21 and a control circuit board 22 connected inside the first housing 21. The first housing 21 provides a mounting position for the first circuit board 12, and the control circuit board 22 is electrically connected to the first circuit board 12 via a connecting wire harness 30. The control circuit board 22 provides the line of sight for the overall function of the driver monitoring system, and the control circuit board 22 can receive and analyze data acquired by the lens assembly 10.

[0044] Furthermore, considering that the control component 20 generates more heat than the lens assembly 10 during practical application, in order to reduce the temperature of the control component 20 during application, the control component 20 also includes a heat sink 23 connected to the outside of the first housing 21. The heat sink 23 is used to improve the heat dissipation efficiency of the control component 20. In order to effectively dissipate the heat generated by the control circuit board 22, the projection of the heat sink 23 on the first housing 21 overlaps with the projection of the control circuit board 22 in the first direction X, preferably overlapping.

[0045] Meanwhile, in order to avoid the first housing 21’s own structure affecting the smooth flow of air through the heat sink 23, the heat sink 23 protrudes from the first housing 21 in the first direction X. When the air flows through the heat sink 23, it will not be obstructed by the first housing 21 and can flow smoothly through the heat sink 23 to carry away the heat generated by the control component 20.

[0046] To guide the airflow through the heat sink 23 and lengthen the airflow path through the first housing 21, multiple heat sinks 23 are provided. Each heat sink 23 protrudes from the first housing 21 along the first direction X. These multiple heat sinks 23 are spaced apart on the outer surface of the first housing 21, forming a first heat dissipation channel 231 extending along the second direction Y and a second heat dissipation channel 232 extending along the third direction Z on the outer surface of the first housing 21. The first heat dissipation channel 231 and the second heat dissipation channel 232 are interconnected, and the first direction X, the second direction Y, and the third direction intersect each other. Preferably, the plane formed by the intersection of the second direction Y and the third direction Z is perpendicular to the first direction X.

[0047] It is understandable that when multiple heat sinks 23 protrude from the first housing 21 along the first direction X, it is equivalent to multiple heat sinks 23 and the first housing 21 being arranged side by side in the first direction X. When airflow passes through the first housing 21, it can directly contact the heat sinks 23. After the airflow contacts the heat sinks 23, the airflow will flow along the multiple heat sinks 23 to form a first heat dissipation channel 231 and a second heat dissipation channel 232 on the outer surface of the first housing 21. By positioning the multiple heat sinks 23 on the first housing 21, the path of the airflow through the heat sinks 23 is guided, which can improve the heat dissipation efficiency of the control component 20. In addition, the first heat dissipation channel 231 and the second heat dissipation channel 232 are interconnected, which can expand the flow range of the airflow when passing through the heat sinks 23, thereby improving the heat dissipation efficiency of the control component 20 and reducing the temperature of the control component 20 during operation.

[0048] Furthermore, the angle between the second direction Y and the third direction Z is an obtuse angle on one side. That is, the angle between the extension direction of the first heat dissipation channel 231 and the extension direction of the second heat dissipation channel 232 is an obtuse angle on one side. Setting the first heat dissipation channel 231 and the second heat dissipation channel 232 in the above manner can improve the airflow velocity inside the first heat dissipation channel 231 and the second heat dissipation channel 232, thereby improving the heat dissipation efficiency of the heat sink 23 for the control component 20 and reducing the temperature of the control component 20 during operation.

[0049] In some embodiments, the plurality of heat sinks 23 further form a third heat dissipation channel 233, the extension direction of the third heat dissipation channel 233 intersecting both the second direction Y and the third direction Z. Optionally, the third heat dissipation channel 233 and the second heat dissipation channel 232 form a V-shaped structure.

[0050] In summary, in this embodiment, the lens assembly 10 and the control assembly 20 are separated, keeping them far apart. This reduces the probability of heat generated by the control assembly 20 being transferred to the lens assembly 10, thereby lowering the temperature of the lens assembly 10 and consequently reducing the probability of the driver accidentally touching the lens assembly 10 and suffering burns. Simultaneously, a heat sink 23 is provided on the outer surface of the first housing 21 to dissipate heat generated by the control circuit board 22, thus reducing the temperature of the control assembly 20 during operation. Specifically, multiple heat sinks 23 protrude from the first housing 21 along a first direction X, forming a first heat dissipation channel 231 extending along a second direction Y and a second heat dissipation channel 232 extending along a third direction Z on the outer surface of the first housing 21. The first heat dissipation channel 231 and the second heat dissipation channel 232 are interconnected. When airflow passes through the first housing 21, because the heat sinks 23 protrude from the first housing 21 along the first direction X, the airflow can directly contact the heat sinks 23. When the airflow comes into contact with the heat sink 23, the airflow will flow along the multiple heat sinks 23 to form a first heat dissipation channel 231 and a second heat dissipation channel 232 on the outer surface of the first housing 21. By positioning the multiple heat sinks 23 on the first housing 21, the path of the airflow through the heat sinks 23 is guided, thereby improving the heat dissipation efficiency of the control component 20. In addition, the first heat dissipation channel 231 and the second heat dissipation channel 232 are interconnected, which can expand the flow range of the airflow when passing through the heat sinks 23, thereby improving the heat dissipation efficiency of the control component 20 and reducing the temperature of the control component 20 during operation.

[0051] In some embodiments, please refer to Figures 1 to 4The control component 20 includes a first heat-conducting element 24, which is connected to the side of the first housing 21 facing the control circuit board 22. The side of the first heat-conducting element 24 away from the first housing 21 abuts against the control circuit board 22. The projection of the first heat-conducting element 24 in the first direction X is inside the projection of the plurality of heat sinks 23 in the first direction X.

[0052] In this embodiment, to protect the components on the control circuit board 22, the components on the control circuit board 22 do not directly contact the first housing 21. Specifically, a first heat-conducting element 24 is provided on the side of the first housing 21 facing the control circuit board 22, and the side of the first heat-conducting element 24 away from the first housing 21 abuts against the control circuit board 22. The first heat-conducting element 24 is used to transfer the heat generated by the control circuit board 22 to the first housing 21, and then dissipates it through the heat sink 23 connected to the first housing 21. To ensure efficient heat dissipation from the control circuit board 22, the projection of the first heat-conducting element 24 in the first direction X is located inside the projection of the multiple heat sinks 23 in the first direction X.

[0053] In actual installation, the hardness of the first heat-conducting element 24 is less than that of the first housing 21 to reduce damage to related components on the control circuit board 22. Alternatively, the first heat-conducting element 24 may also have a certain degree of elasticity to effectively protect the related components on the control circuit board 22. For example, the first heat-conducting element 24 may be configured as a thermally conductive silicone sheet or a thermally conductive gel.

[0054] In some embodiments, a partition rib 2121 protrudes from the interior of the first housing 21 along a first direction X, dividing the interior of the first housing 21 into a first cavity 2122 and a second cavity 2123 arranged side by side along a fourth direction L, the fourth direction L intersecting the first direction X. The control circuit board 22 includes a main body portion 221 and a connecting portion 222 connected to each other, the projection of the main body portion 221 in the first direction X being located inside the first cavity 2122, and the projection of the connecting portion 222 in the first direction X being located inside the second cavity 2123.

[0055] The control circuit board 22 has a main body 221 that performs specific main functions and a connecting part 222 for connecting with other structures. The main body 221 and the connecting part 222 are interconnected. The main body 221 dissipates a lot of heat, and the heat generated by the main body 221 should not be transferred to the vicinity of the connecting part 222.

[0056] Therefore, a partition rib 2121 protrudes along the first direction X inside the first housing 21, dividing the interior of the first housing 21 into a first cavity 2122 and a second cavity 2123. When the control circuit board 22 is connected to the first housing 21, the projection of the main body 221 in the first direction X is inside the first cavity 2122, and the projection of the connecting part 222 in the first direction X is inside the second cavity 2123. By placing the main body 221 and the connecting part 222 in different cavities, the probability of heat generated by the main body being transferred to the connecting part 222 can be reduced, thus reducing the impact of the main body 221 on the connecting part 222.

[0057] In some embodiments, the first housing 21 includes a first housing body 211 and a second housing body 212 separately disposed in a first direction X. The first housing body 211 and the second housing body 212 are recessed in a direction away from each other to form a receiving cavity, and the control circuit board 22 is located inside the receiving cavity. Optionally, a heat sink 23 is disposed on the first housing body 211. The first housing body 211 is made of die-cast aluminum and has a heat-reinforcing coating on its surface. The control circuit board 22 transfers heat to the first housing body 211 through a copper-plated window on the chip's packaging surface and its own surface, and through a first heat-conducting element 24. A partition rib 2121 is disposed on the second housing body 212, and the partition rib 2121 separates the recessed portion of the second housing body 212. The control circuit board 22 can be connected to the partition rib 2121.

[0058] In some embodiments, please refer to Figures 1 to 5 The lens assembly 10 includes a lens bracket 13, a lens body 11 connected to the lens bracket 13 and extending along the fifth direction M to one side of the lens bracket 13, and a first circuit board 12 connected to the side of the lens bracket 13 opposite to the lens body 11 in the fifth direction M.

[0059] In this embodiment, both the lens body 11 and the first circuit board 12 are connected to the lens bracket 13 to ensure the connection stability between the lens body 11 and the first circuit board 12. The lens bracket 13 has two opposing sides along the fifth direction M, one side of which is connected to the lens body 11 and the other side is connected to the first circuit board 12. Since the lens assembly 10 and the control assembly 20 are separate components and are relatively independent structures during installation, the orientation of related structures on them is not specifically related. The fifth direction M may or may not be consistent with the first direction X.

[0060] In some embodiments, a connector 131 is provided on the lens bracket 13. Both ends of the connector 131 protrude from the lens bracket 13 along the fifth direction M. A connector hole 1311 is provided through the connector 131 along the fifth direction M. Part of the lens body 11 is located inside the connector hole 1311. One end of the lens body 11 passes through the connector hole 1311 and is connected to the first circuit board 12.

[0061] To improve the connection stability of the lens body 11 on the lens bracket 13, a connector 131 adapted to the lens body 11 is provided on the lens bracket 13. The connector 131 has a connector hole 1311, and part of the lens body 11 can be placed inside the connector hole 1311. The connection stability of the lens body 11 on the lens bracket 13 is improved by limiting the position of the lens body 11 by the connector 131. Optionally, the lens body 11 is glued to the connector 131.

[0062] In some embodiments, the connector 131 has an elastic pad 132 at one end facing the first circuit board 12 in the fifth direction M. The elastic pad 132 is connected to the connector 131, and the side of the elastic pad 132 facing away from the connector 131 abuts against the first circuit board 12.

[0063] In this embodiment, to protect the components on the first circuit board 12, an elastic pad 132 is provided between the first circuit board 12 and the connector 131 to reduce damage to the components on the first circuit board 12 caused by the connector 131. Furthermore, the elastic pad 132 can be in the form of an elastic ring, with a portion of the elastic ring fitted outside the connector 131, and the end of the elastic ring away from the connector 131 abutting against the first circuit board 12. The elastic ring effectively encloses a certain space outside the connector 131, which directly corresponds to the chip on the first circuit board 12, reducing the probability of dust and other particles contacting the chip and providing some protection.

[0064] In some embodiments, the lens assembly 10 further includes a light source 141, which is connected to the lens bracket 13 and is located on the same side of the lens bracket 13 in the fifth direction M. The light source 141 is disposed on one side of the lens body 11 along the sixth direction N, where the fifth direction M intersects the sixth direction N.

[0065] In practical applications, the lens assembly 10 inevitably operates in environments with insufficient light. To ensure the shooting effect of the lens body 11, in this embodiment, a light source 141 is provided around the lens body 11 to supplement the light and improve the shooting effect of the lens body 11. The light source 141 and the lens body 11 are located on the same side of the lens bracket 13 to make full use of the light to supplement the light for the lens body 11 during shooting.

[0066] In some embodiments, the lens assembly 10 further includes a light-shielding member 15, which is connected to the lens bracket 13 and located on the side of the lens body 11 facing away from the lens bracket 13 in the fifth direction M. The light-shielding member 15 has a light-transmitting area, the projection of a portion of the light-transmitting area in the fifth direction M coincides with the projection of the lens body 11 in the fifth direction M, and the projection of a portion of the light-transmitting area in the fifth direction M coincides with the projection of the light source 141 in the first direction X.

[0067] In practical applications, the lens assembly 10 inevitably encounters environments with excessively strong light. To ensure the shooting effect of the lens body 11, in this embodiment, a light-shielding member 15 is provided around the lens body 11 to block light and improve the shooting effect of the lens body 11. A corresponding light-transmitting area is provided on the light-shielding member 15 to enable the lens body 11 and the light source 141 to operate normally.

[0068] Regarding the setting of the light source 141, in some embodiments, in order to ensure the balance of light, a light source 141 is respectively set on both sides of the lens body 11 along the sixth direction N. Correspondingly, three light-transmitting areas are set on the light-shielding member 15, one light-transmitting area corresponds to the lens body 11, and the other two light-transmitting areas correspond to the two light sources 141 respectively.

[0069] In some embodiments, the lens assembly 10 includes a second circuit board 14, a light source 141 disposed on the second circuit board 14, and a lens bracket 13 protruding along the fifth direction M with a first protrusion 133, the second circuit board 14 being connected to the first protrusion 133. A second heat-conducting element 135 protrudes along the fifth direction M from the lens bracket 13, the side of the second heat-conducting element 135 facing away from the lens bracket 13 abutting against the second circuit board 14, and the projection of the second heat-conducting element 135 in the fifth direction M overlapping the projection of the light source 141 in the fifth direction M.

[0070] In order to stably position the light source 141, a second circuit board 14 is provided on the light source 141 and connected to the lens bracket 13 through the second circuit board 14 to ensure the positional stability of the light source 141 relative to the lens bracket 13, thereby ensuring the positional stability of the light source 141 relative to the lens body 11.

[0071] Considering that the lens body 11 protrudes from the lens bracket 13 along the fifth direction M, in order to ensure the effect of the light source 141, the second circuit board 14 also protrudes from the lens bracket 13 along the fifth direction M, thereby causing the light source 141 to protrude from the lens bracket 13 along the fifth direction M. Specifically, a first protrusion 133 is provided on the lens bracket 13, and the first protrusion 133 protrudes from between the lenses along the fifth direction M, and the second circuit board 14 is connected to the first protrusion 133. Optionally, a second protrusion 134 can also be provided on the lens bracket 13, and both the second protrusion 134 and the first protrusion 133 protrude from the lens bracket 13 along the fifth direction M. The first protrusion 133 and the second protrusion 134 are spaced apart in the sixth direction N.

[0072] To address the heat dissipation issue of the light source 141, a second heat-conducting component 135 is provided on the lens bracket 13. The second heat-conducting component 135 protrudes from the lens bracket 13 along the fifth direction M. The second circuit board 14 abuts against the side of the second heat-conducting component 135 facing away from the lens bracket 13. The projection of the second heat-conducting component 135 in the fifth direction M overlaps with the projection of the light source 141 in the fifth direction M. The structure and material of the second heat-conducting component 135 are similar to those of the first heat-conducting component 24, and will not be described further here.

[0073] When the lens bracket 13 is provided with a first protrusion 133 and a second protrusion 134, the light source 141 is located between the first protrusion 133 and the second protrusion 134, and the second heat-conducting element 135 is also located between the first protrusion 133 and the second protrusion 134.

[0074] In some embodiments, please refer to Figures 1 to 6 The lens assembly 10 includes a second housing 16, which serves as the outermost structure of the lens assembly 10 and houses the remaining structures within it. The second housing 16 includes a third housing body 161 and a fourth housing body 162, which are separately disposed along a fifth direction M. Both the third housing body 161 and the fourth housing body 162 are recessed away from each other, and when connected, they enclose and protect the remaining structures within the lens assembly 10. Optionally, a light-shielding member 15 is connected to the third housing body 161 via an adhesive paper 1611. Corresponding light-transmitting holes are provided on the third housing body 161 and the adhesive paper 1611 for the light-transmitting areas on the light-shielding member 15.

[0075] In some embodiments, to facilitate the installation and connection of the lens assembly 10, positioning posts can be provided on the lens bracket 13, and positioning holes can be provided on both the first circuit board 12 and the second circuit board 14. The positioning posts and positioning holes cooperate with each other to achieve the initial positioning of the first circuit board 12 and the second circuit board 14 relative to the lens bracket 13, and then the first circuit board 12 and the second circuit board 14 are connected to the lens bracket 13. The connection between the third housing body 161 and the fourth housing body 162 follows the same principle and will not be described in detail here.

[0076] Secondly, this application provides a vehicle including the aforementioned driver monitoring system. The lens assembly 10 can be mounted on the A-pillar or steering column of the vehicle to ensure effective monitoring of the entire cockpit by positioning the lens body 11. The lens body 11 is located inside the light-shielding member 15, making it invisible from inside the cockpit. The lens body 11 can observe the driver and other areas inside the vehicle through the light-transmitting area on the light-shielding member 15. Light from the light source 141 can pass through the light-transmitting area from inside the lens assembly 10 to the outside of the lens assembly 10.

[0077] The control component 20 can be installed inside the passenger-side glove box to reduce the probability of accidental activation by occupants. For the installation of the control component 20, a corresponding snap-fit ​​structure and guide structure can be provided on the first housing 21. First, the guide structure moves the first housing 21 to the installation position, and then the snap-fit ​​structure secures the control component 20 to the vehicle body. Optionally, the first housing 21 can also be connected to the vehicle body using screws or bolts.

[0078] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
