Description
Technical Field
[0001] This utility model relates to the field of video surveillance processing equipment technology, specifically to a vehicle-mounted DMS camera structure with a privacy sliding cover switch. Background Technology
[0002] A vehicle-mounted DMS (Driver Monitoring System) camera is a video monitoring and processing device used in vehicles. It is one of the core components of intelligent vehicle safety technology, mainly preventing traffic accidents caused by fatigue, distraction, etc. by monitoring the driver's status in real time.
[0003] Vehicle-mounted DMS cameras, through precise visual perception, act as "sentinels" protecting driving safety—providing dynamic protection throughout the entire journey, from physiological fatigue to behavioral risks. Installation locations must strictly adhere to angle and distance specifications to ensure reliability, while technological integration (such as infrared imaging) and regulatory requirements are driving their development towards intelligence and concealment. In the future, with deeper integration with in-cabin OMS and external vehicle interaction, DMS will not only be a safety tool but also a core hub for human-vehicle co-driving.
[0004] In existing technologies, in-vehicle DMS cameras continuously collect information from the driver. However, in certain situations, such as when the driver is resting in the car, the driver often does not want the in-vehicle DMS camera to collect information. Considering the overall appearance, existing technologies often lack a physical switch to turn off the in-vehicle DMS camera, which can easily lead to privacy leaks and information security risks. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is: how to provide a vehicle DMS camera structure with a privacy sliding cover switch that can effectively turn off the vehicle DMS camera when it is not needed for information collection, thereby avoiding privacy leakage and information security risks.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A vehicle-mounted DMS camera structure with a privacy sliding cover switch includes an outer housing, a filter, and a sliding switch. The outer housing and the filter are connected, forming a receiving cavity between them. A sensor plate is disposed within the receiving cavity and fixed to the outer housing. A lens mount is disposed on the sensor plate, and a camera is mounted on the lens mount. The sliding switch is slidably connected to the outer housing. A first mounting groove and a second mounting groove are formed on the outer housing at the position where the sliding switch connects. The first mounting groove is located on the outer surface of the outer housing, and the second mounting groove extends outward from the inner surface of the outer housing and communicates with the first mounting groove. The length and width of the second mounting groove are both smaller than those of the first mounting groove, forming a positioning step at the position where the first and second mounting grooves connect. The device includes a head, a connecting part, and a blocking part. The head is located in the first mounting groove and abuts against the positioning step. The connecting part is located in the second mounting groove. The sliding dimension of the head is smaller than the dimension of the corresponding direction of the first mounting groove, and the sliding dimension of the connecting part is smaller than the dimension of the corresponding direction of the second mounting groove, so that the head can slide in the first mounting groove, the connecting part can slide in the second mounting groove, and the sliding distance of the head is smaller than the dimension of the positioning step at the corresponding position, so that the head always stays on the positioning step. The blocking part extends into the receiving cavity at the position corresponding to the camera, and when the head slides, it can drive the blocking part to move between a first position and a second position. The first position is the position where the blocking part does not block the camera at all, and the second position is the position where the blocking part completely blocks the camera.
[0008] The working principle of this invention is as follows: This solution uses a sliding switch to completely shut down the vehicle-mounted DMS camera when it is not needed for information collection. Specifically, when the vehicle-mounted DMS camera needs to collect driver information normally, the operator applies force to the sliding switch head, moving the obstruction part from the second position to the first position. At this time, the obstruction part does not block the camera's position, and the camera collects driver information normally. When the driver is resting in the car or when information collection by the vehicle-mounted DMS camera is not needed, the operator applies force to the sliding switch head again, moving the obstruction part from the first position to the second position. This time, the obstruction part completely blocks the camera, preventing it from collecting driver information. Therefore, the vehicle-mounted DMS camera can be effectively shut down when information collection is not needed, thereby avoiding privacy leaks and information security risks.
[0009] Preferably, the vehicle-mounted DMS camera structure also includes an LED light board, in which a groove is formed and an LED light is installed, and thermally conductive silicone is attached to the LED light board.
[0010] In this way, by actively emitting infrared light of a specific wavelength, the LED light can provide a stable imaging light source for the camera in all weather conditions, ensuring accurate capture of facial biometric features in complex scenarios such as darkness, bright light, or when the driver is wearing sunglasses. At the same time, the LED light generates a significant amount of heat during operation; attaching thermally conductive silicone to the LED light panel provides excellent heat dissipation, preventing damage caused by overheating.
[0011] Preferably, a contact switch is also provided on the side wall of the first mounting groove. The contact switch is connected in series with the LED light. When the shielding part is in the first position, the head abuts against the contact switch. When the shielding part is in the second position, the head separates from the contact switch.
[0012] In this way, by setting a contact switch, when the obstruction part is in the first position, the vehicle-mounted DMS camera needs to collect driver information normally. At this time, the head of the sliding switch abuts against the contact switch, the contact switch is in the closed state, and the circuit containing the LED light is turned on. When the obstruction part is in the second position, the vehicle-mounted DMS camera does not need to collect driver information. At this time, the head separates from the contact switch, the contact switch is in the open state, the circuit containing the LED light is disconnected, and the LED light does not work. As the main heat-generating component in the vehicle-mounted DMS camera, disconnecting the LED light circuit when the vehicle-mounted DMS camera is not in use can greatly reduce the heat generation of the entire vehicle-mounted DMS camera and improve its service life.
[0013] Preferably, the side of the head facing the outer surface of the outer casing is flush with the outer surface of the outer casing.
[0014] In this way, the side of the head facing the outer surface of the outer casing is flush with the outer surface of the outer casing, while the head, connecting part and shielding part are embedded in the outer casing. This built-in installation method makes the overall appearance beautiful and the size compact.
[0015] Preferably, a first mark and a second mark are provided on the outer casing at the position corresponding to the sliding switch, with the first mark located on the side closer to the contact switch and the second mark located on the side farther away from the contact switch.
[0016] In this way, by setting the first and second indicators, the operator can intuitively determine the current working status of the vehicle-mounted DMS camera based on the positional relationship between the sliding switch, the first indicator, and the second indicator.
[0017] Preferably, when the shielding part is in the first position, the head abuts against one side wall of the first mounting groove; when the shielding part is in the second position, the head abuts against the other side wall of the first mounting groove.
[0018] In this way, when the shielding part is in the first position or the second position, the head abuts against the two side walls of the first mounting groove, and the two side walls of the first mounting groove can be used to limit the sliding of the head, while also ensuring that the shielding part can move to the correct position.
[0019] Preferably, the filter is made of a black optical material that transmits red light at 940nm.
[0020] Preferably, the thermal conductivity of the thermally conductive silicone is 3W.
[0021] Preferably, the filter is fixedly connected to the outer casing by screws.
[0022] Preferably, a plurality of friction grooves are provided on the side of the head facing the outer surface of the outer casing.
[0023] In this way, the friction groove can increase the friction force when the operator operates the head, thereby improving the comfort and convenience of operation.
[0024] Compared with the prior art, this utility model uses an internal sliding switch to block the imaging lens, ensuring that the image is completely physically closed and avoiding the leakage of facial information. At the same time, the sliding switch is built into the back of the filter, which is aesthetically pleasing and space-saving. Attached Figure Description

[0033] In-vehicle DMS (Driver Monitoring System) cameras are a core component of intelligent vehicle safety technology, primarily preventing traffic accidents caused by fatigue, distraction, and other factors by monitoring the driver's condition in real time. However, in certain situations, such as when the driver is resting in the vehicle, the driver often does not want the in-vehicle DMS camera to collect information. Current technology, considering the overall aesthetics, often lacks a physical switch to turn off the in-vehicle DMS camera, which can easily lead to privacy leaks and information security risks.
[0034] To address the aforementioned problems in the prior art, this specific embodiment provides a vehicle-mounted DMS camera structure with a privacy sliding cover switch, as shown in the attached figure. Figure 1 To the attached Figure 4 As shown, it includes an outer casing 1, a filter 2, an LED light board 7, a sensor board 4, a first fixing bracket 10, a second fixing bracket 11, and a sliding switch 3. The outer casing 1 and the filter 2 are fixedly connected by screws 9, and a receiving cavity is formed between the outer casing 1 and the filter 2. The filter 2 is made of a black optical material that transmits 940nm red light. The LED light board 7, the sensor board 4, the first fixing bracket 10, the second fixing bracket 11, and the sliding switch 3 are all disposed in the receiving cavity.
[0035] The LED light panel 7 has a groove in which an LED light is installed. Thermally conductive silicone 8, with a thermal conductivity of 3W, is also attached to the LED light panel 7. The LED light actively emits infrared light of a specific wavelength, providing a stable imaging light source for the camera 6 in all weather conditions, ensuring accurate capture of facial biometric features in complex scenarios such as darkness, bright light, or when the driver is wearing sunglasses. Simultaneously, the LED light generates a significant amount of heat during operation; the thermally conductive silicone 8 on the LED light panel 7 effectively dissipates heat, preventing damage caused by overheating.
[0036] Sensor board 4 is fixed on the outer casing 1. Sensor board 4 is also called infrared image sensor main board or DMS image processing board. Its core function is to carry the CMOS / CCD infrared image sensor, convert the optical signals of the driver's face into electrical signals, and perform primary noise reduction / enhancement processing. A mirror mount 5 is set on sensor board 4, and a camera 6 is set on mirror mount 5.
[0037] For example, see appendix. Figure 3 and attached Figure 4As shown, the slide switch 3 is slidably connected to the outer casing 1. A first mounting groove and a second mounting groove are provided on the outer casing 1 at the position where the slide switch 3 connects. The first mounting groove is located on the outer surface of the outer casing 1, and the second mounting groove extends outward from the inner surface of the outer casing 1 and communicates with the first mounting groove. The length and width of the second mounting groove are both smaller than those of the first mounting groove, forming a positioning step 101 at the position where the first and second mounting grooves connect. The slide switch 3 includes a head 301, a connecting part 302, and a blocking part 303. The head 301 is located in the first mounting groove and abuts against the positioning step 101. The connecting part 302 is located in the second mounting groove. The dimension of the head 301 in the sliding direction is smaller than that of the first mounting groove. The dimensions of the mounting slot in the corresponding direction and the dimensions of the connecting part 302 in the sliding direction are smaller than the dimensions of the second mounting slot in the corresponding direction, so that the head 301 can slide in the first mounting slot and the connecting part 302 can slide in the second mounting slot. The sliding distance of the head 301 is less than the dimensions of the positioning step 101 at the corresponding position, so that the head 301 always stays on the positioning step 101. The shielding part 303 extends into the receiving cavity at the position corresponding to the camera 6. When the head 301 slides, it can drive the shielding part 303 to move between the first position and the second position. The first position is the position where the shielding part 303 does not shield the camera 6 at all, and the second position is the position where the shielding part 303 completely shields the camera 6.
[0038] In this embodiment, a contact switch (not shown) is also provided on the side wall of the first mounting slot. The contact switch is connected in series with the LED light. When the shielding part 303 is in the first position, the head 301 abuts against the contact switch. When the shielding part 303 is in the second position, the head 301 separates from the contact switch. By setting the contact switch, when the shielding part 303 is in the first position, the vehicle-mounted DMS camera needs to collect driver information normally. The head 301 of the sliding switch 3 abuts against the contact switch, the contact switch is in the closed state, and the circuit of the LED light is turned on. When the shielding part 303 is in the second position, the vehicle-mounted DMS camera does not need to collect driver information. At this time, the head 301 separates from the contact switch, the contact switch is in the open state, the circuit of the LED light is disconnected, and the LED light does not work. As the main heat-generating component in the vehicle-mounted DMS camera, disconnecting the LED light circuit when the vehicle-mounted DMS camera is not needed can greatly reduce the heat generation of the entire vehicle-mounted DMS camera and improve its service life.
[0039] In this embodiment, the side of the head 301 facing the outer surface of the outer casing 1 is flush with the outer surface of the outer casing 1. Simultaneously, multiple friction grooves 304 are provided on the side of the head 301 facing the outer surface of the outer casing 1. The head 301, connecting portion 302, and shielding portion 303 are embedded within the outer casing 1. This built-in installation method results in an aesthetically pleasing overall appearance and compact size. The friction grooves 304 increase the friction force when the operator operates the head 301, improving operational comfort and convenience.
[0040] For example, see appendix. Figure 4 As shown, in this embodiment, a first indicator 102 (e.g., ON) and a second indicator 103 (e.g., OFF) are provided on the outer casing 1 at the position corresponding to the sliding switch 3. The first indicator 102 is located on the side closer to the contact switch, and the second indicator 103 is located on the side farther away from the contact switch. By setting the first indicator 102 and the second indicator 103, the operator can intuitively determine the current working status of the vehicle-mounted DMS camera based on the positional relationship between the sliding switch 3, the first indicator 102, and the second indicator 103.
[0041] In this embodiment, when the blocking part 303 is in the first position, the head 301 abuts against one side wall of the first mounting groove; when the blocking part 303 is in the second position, the head 301 abuts against the other side wall of the first mounting groove. When the blocking part 303 is in either the first or second position, the head 301 abuts against both side walls of the first mounting groove. This utilizes the side walls of the first mounting groove to limit the sliding of the head 301, while also ensuring that the blocking part 303 can move to the correct position.
[0042] When the vehicle-mounted DMS camera in this solution is working, its LED light emits infrared light of a specific wavelength, providing a stable imaging light source for camera 6 in all weather conditions. This ensures accurate capture of facial biometric features in complex scenarios such as darkness, bright light, or when the driver is wearing sunglasses. Camera 6 then collects the driver's information, and the collected data is transmitted to sensor board 4 for processing. The processed data from sensor board 4 is further transmitted to an external controller for further processing. Additionally, this solution incorporates a sliding switch 3, which allows the vehicle-mounted DMS camera to be completely shut off when information collection is not required. Specifically, when the vehicle-mounted DMS camera needs to collect driver information normally, the operator activates the head 301 of the sliding switch 3, moving the blocking part 303 from the second position to the first position. At this time, the blocking part 303 does not obstruct the position of the camera 6, and the camera 6 collects driver information normally. When the driver is resting in the car or when the vehicle-mounted DMS camera does not need to collect information, the operator activates the head 301 of the sliding switch 3 again, moving the blocking part 303 from the first position to the second position. At this time, the blocking part 303 completely blocks the camera 6, preventing the camera 6 from collecting driver information. This effectively turns off the vehicle-mounted DMS camera when it is not needed, thus avoiding privacy leaks and information security risks.
[0043] Compared with the prior art, this utility model uses an internally manufactured sliding switch 3 to block the imaging lens, ensuring that the image is completely physically closed and avoiding the leakage of facial information. At the same time, the sliding switch 3 is built into the back of the filter 2, which is aesthetically pleasing and space-saving.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
