Description

Technical Field

[0001] This utility model belongs to the field of intelligent monitoring equipment, specifically relating to a device for simultaneous dual-channel, multi-angle monitoring in automotive intelligent cockpit applications, and particularly a small intelligent IP camera with ADAS and DMS. Background Technology

[0002] Cameras are commonly used surveillance devices that can continuously monitor a fixed angle. Users simply need to mount the camera on a fixed surface to monitor the area in front of the camera lens. In the increasingly intelligent automotive field, the functional requirements of cameras are also more complex. Some manufacturers can already integrate ADAS functions, but the corresponding housing size has doubled.

[0003] To monitor targets inside and outside the vehicle, multiple cameras need to be fixed at different angles. Therefore, many vehicles on the market have multiple independent camera devices installed inside. They are usually mounted at a fixed angle using a housing base. However, with this design, the angle cannot be adjusted after installation, requiring multiple cameras to shoot from different angles. Furthermore, it is impossible to simultaneously monitor the driver's status inside the vehicle and monitor the driving situation outside the vehicle in real time.

[0004] Cameras typically feature large-capacity hardware storage, image processing systems, high-definition lenses, and housings. However, in intelligent automotive driver monitoring applications, they suffer from poor usability, large space requirements, a subpar user experience, and high costs. Therefore, there is an urgent need for a compact, easily installable camera that combines ADAS (Advanced Driver Assistance Systems) functionality with a driver monitoring system (DMS) to address these issues. Summary of the Invention

[0005] Purpose of the utility model: The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a dual-channel IP camera that includes ADAS and DMS functions, thereby reducing the number of cameras required, reducing costs, improving installation convenience, increasing integration, adding the ability to simultaneously monitor targets inside and outside the vehicle, and improving security.

[0012] Furthermore, the ADAS lens module includes an ADAS lens, an ADAS lens mounting aluminum frame, and an aluminum frame rotating wheel. The ADAS lens mounting aluminum frame is a semi-cylindrical hollow tube with an open top, and rotating shafts are provided at both ends. One end of the rotating shaft is rotatably installed at the ADAS lens mounting slot, and the other end of the rotating shaft is rotatably installed inside the outer casing, so that the ADAS lens mounting aluminum frame can rotate around the rotating shafts. The ADAS lens is installed at the bottom of the ADAS lens mounting aluminum frame, and the aluminum frame rotating wheel is located on one side of the ADAS lens mounting aluminum frame. Rotating the aluminum frame rotating wheel drives the ADAS lens mounting aluminum frame and the ADAS lens to rotate together.

[0013] Furthermore, a dial window is provided on the top side of the housing to expose the aluminum frame wheel, which can be turned from the outside to make the ADAS lens mounting aluminum frame and ADAS lens rotate together to adjust the shooting angle.

[0014] Furthermore, the data processing module includes a hardware circuit board, a microphone, a memory, a connector, and a processing chip; the connector is connected to the DMS camera lens module and the ADAS lens module via a data cable.

[0015] Furthermore, it also includes a fixed base, on the top of which is a set of buckles that are snapped into the bottom of the inner shell; a set of adhesive strips are pasted on the bottom surface of the fixed base, and a notch for the movement of the ADAS lens is reserved in the middle.

[0034] The present invention can be better understood from the following embodiments.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance.

[0036] like Figure 1 and Figure 4 As shown, this utility model discloses a small intelligent IP camera with ADAS and DMS, comprising a housing 10, an inner housing 20, a DMS camera lens module 30, an ADAS lens module 40, and a data processing module 50; the DMS camera lens module 30, the ADAS lens module 40, and the data processing module 50 are all installed in the inner housing 20; the housing 10 covers the inner housing 20; the DMS camera of the DMS camera lens module 30 protrudes from the top of the housing 10 and is rotatable; the ADAS lens of the ADAS lens module 40 protrudes from the bottom of the inner housing 20 and is rotatable.

[0037] Combination Figure 2 and Figure 3 As shown, the inner shell 20 of the intelligent IP camera is provided with a DMS camera lens mounting part 201 for the DMS camera lens module 30 and an ADAS lens mounting slot 202 for the ADAS lens module 40. One end of the outer shell 10 has a DMS camera lens mounting window 101 exposing the DMS camera lens module 30, and the bottom of the outer shell 10 is open, allowing the ADAS lens module 40 to be exposed. The cross-section of the outer shell 10 is trapezoidal; in other embodiments, the cross-section can also be circular, regular polygonal, etc. The outer shell 10 and the inner shell 20 have two symmetrical parts, forming a space between them to accommodate a two-channel camera circuit board, lens, and wiring harness. Because a dual-core CPU is used for camera data processing, the ADAS lens and DMS lens can be placed within a very small shell, and the relevant data can be processed through a small hardware development board, thus greatly reducing the camera's size.

[0038] like Figure 5 As shown, the DMS camera lens module 30 includes a DMS lens 301, a DMS lens mounting aluminum frame 302, and a DMS lens rotating bracket 303. The DMS lens 301 is fixed to the lower DMS lens mounting aluminum frame 302 by a set of screws. The DMS lens mounting aluminum frame 302 is rotatably mounted in the DMS lens rotating bracket 303 and can rotate together with the DMS lens 301. The DMS lens rotating bracket 303 is mounted in the DMS camera lens mounting part 201 by screws and is connected to the outer shell 10 together with the plastic bracket through the Y-shaped slot.

[0039] Combination Figure 4 As shown, the DMS lens rotating bracket 303 has three conventional threaded posts, which can be used to fix the DMS lens rotating bracket 303, the DMS lens fixing aluminum bracket 302, and the DMS lens 301 together to the outer shell 10. The DMS lens rotating bracket 303 has a fan-shaped cutout so that the DMS lens 301 can be rotated within a certain angle. The six long threaded posts on the outer shell 10 are for inserting long screws into the six corresponding holes on the inner shell 20, thereby fixing the inner shell 20 and the outer shell 10.

[0040] In some embodiments, a set of limiting protrusions 304 are provided on the outer side of the housing of the DMS lens 301. The limiting protrusions 304 limit the rotation of the DMS lens 301 along the periphery of the DMS camera lens mounting window 101. The periphery of the DMS camera lens mounting window 101 is provided with a scale for displaying the rotation angle of the DMS lens 301. The lens frame can be manually adjusted, with 6 positions selectable on both the X and Y axes. The overall rotatable angle is 50 degrees horizontally and 60 degrees diagonally.

[0041] In some embodiments, the inner side of the DMS lens rotating bracket 303 is provided with a lead port 305 for mounting the DMS lens 301 data cable.

[0042] like Figure 6 As shown, the ADAS lens module 40 includes an ADAS lens 401, an ADAS lens mounting aluminum frame 402, and an aluminum frame rotating wheel 403. The ADAS lens mounting aluminum frame 402 is a semi-cylindrical hollow tube with an open top, and rotating shafts 404 are respectively provided at both ends. One end of the rotating shaft is rotatably mounted at the ADAS lens mounting slot 202, and the other end of the rotating shaft is rotatably mounted inside the outer casing 10, so that the ADAS lens mounting aluminum frame 402 can rotate around the rotating shaft 404. The ADAS lens 401 is mounted at the bottom of the ADAS lens mounting aluminum frame 402, and the aluminum frame rotating wheel 403 is located on one side of the ADAS lens mounting aluminum frame 402. By rotating the aluminum frame rotating wheel 403, the ADAS lens mounting aluminum frame 402 and the ADAS lens 401 rotate together. The overall ADAS lens mounting aluminum frame 402 can rotate at a horizontal angle of 70 degrees and an effective angle of 80 degrees.

[0043] Combination Figure 1 and Figure 4 The top side of the housing 10 is provided with a dial window 102 that exposes the aluminum frame wheel 403, which can be turned from the outside to make the ADAS lens mounting aluminum frame 402 and ADAS lens 401 rotate together to adjust the shooting angle.

[0044] To prevent the data processing module 50 from affecting the wiring harness after installation, the ADAS lens module 40 adopts a semi-cylindrical design and is fixed to the data processing module 50 by screw posts. The pivot at the bottom of the ADAS lens module 40 is locked by the Y-shaped buckle of the plastic bracket, which prevents it from wobbling up and down and ensures that the lens does not shake.

[0045] The camera can communicate with the vehicle host via a wiring harness, which will inevitably involve a cable and a connector. To prevent the connector from wobbling, a slender slot for accommodating the connector is provided in the middle of the lower part of the ADAS lens mounting bracket 402. A lead-in port 305 is also provided on the hemispherical DMS lens rotating bracket 303 for this function.

[0046] In existing technologies, the hardware circuit board and lens can generally only be fixed at designated positions on the inner shell of a camera, and when the camera is in operation, the lens can only point at a fixed angle to capture images. However, in this embodiment, as... Figure 4 The DMS lens 301 and ADAS lens 401 can switch between different camera angles by toggling the knob and lens frame, providing excellent installation and adjustment space.

[0047] In this embodiment, the data processing module 50 includes a hardware circuit board, a microphone, a memory, a connector, and a processing chip; the connector is connected to the DMS camera lens module 30 and the ADAS lens module 40 via a data cable.

[0048] In this embodiment, the intelligent IP camera also includes a mounting base 60. A set of clips 601 are provided on the top of the mounting base 60, which are used to engage with the bottom of the inner shell 20. A set of adhesive strips is pasted on the bottom surface of the mounting base 60, with a notch in the middle for the ADAS lens to move. Simply attach the mounting base 60 to the windshield using 3M adhesive, then assemble the inner shell 20 and outer shell 10 of the camera, and attach them to the mounting base 60 using L-shaped clips. During operation, only the knob or the ADAS lens needs to be adjusted to position it in front of the vehicle. If the camera needs to be removed, simply disconnect the connection between the inner shell 20 and the mounting base 60, and move the camera in the opposite direction.

[0049] Combination Figure 1 and Figure 4 The outer shell 10 and the inner shell 20 are connected and fixed by a set of screw posts; a wire harness hole 103 is provided on one side of the outer shell 10 for leading out all wire harnesses, and all wire harnesses are led out from the wire harness hole 103 of the outer shell 1.

[0050] like Figure 1 As shown, both sides of the outer shell 10 and the inner shell 20 have raised and recessed points, which can provide good friction, make disassembly and installation easier, and also improve the appearance.

[0051] Combination Figure 7 and Figure 8The diagram illustrates the overall circuit structure of the dual-channel IP camera. The high-frequency dual-core CPU processor CV1811C is primarily used to process relevant image data and store it in real-time into the large-capacity TF-CARD hardware storage device. Image data acquired by both the DMS and ADAS lens modules must undergo rapid H.264 / H.265 encoding and decoding by the CV1811C processor.

[0052] The DMS lens module and the processor communicate via IIC, allowing control of the DMS lens module. The image information captured by the controlled DMS lens can be fed back to the processor via MIPI communication. It has a resolution of up to 1280 (H) × 720 (V), an effective pixel count of 720P, supports automatic white balance and backlight compensation, has an effective infrared range of 1-2m, and the tilt angle can be manually adjusted.

[0053] The ADAS lens module and the processor communicate via IIC, allowing control of the ADAS lens module. The image information captured by the controlled ADAS lens can be fed back to the processor via MIPI communication. It has an effective resolution of 1920 (H) x 1080 (V), an effective pixel count of 1080P, and supports color images, automatic white balance and backlight compensation. The tilt angle can be manually adjusted.

[0054] In this embodiment, the dual-channel IP camera also supports WIFI wireless transmission mode, as well as Ethernet interface and USB-OTG upgrades. When the product is powered on, the default initialization firmware is stored in SPI-NAND-Flash.

[0055] In this embodiment, both the microphone (MIC) and the speaker (SPK) are soldered onto a hardware circuit board. Figure 8 As shown, the ADAS lens module is soldered to the back of the hardware circuit board and can be directly mounted on the semi-cylindrical aluminum frame. The DMS lens module, however, needs to be connected to the plug-in on the hardware circuit board J501 via a flexible flat cable.

[0056] This utility model has a simple structure and is easy to use. It improves the intelligence level of cameras on vehicle platforms, realizes a highly integrated dual-channel camera group, and allows independent adjustment of the camera lens angle. It solves the problems of fixed ADAS camera angle and inability of DMS lens to be integrated with ADAS module in the prior art, saving costs and improving installation convenience.

[0057] Installation and disassembly process:

[0058] 1) First, peel off the 3M adhesive on the mounting base 60 and stick it to the windshield; then, use screws to align the outer shell 10 and inner shell 20 until they are screwed in and cannot be turned. With the inner and outer shells integrated, the outer shell 10 facing outwards, and the five L-shaped clips of the inner shell 20 aligned with the positions on the mounting base 60. Slowly push them parallel until a clicking sound is heard and they cannot be pushed any further. At this point, the device is locked and cannot be flipped. The installation is now complete.

[0059] 2) To unlock the device, press the surface of the outer casing with your palm and push it parallel to the opposite direction of the L-shaped buckle, and then gently lift it up. Since the base is already fixed, you only need to lift the outer casing to the large notch of the L-shaped opening. At this time, the buckle will no longer be under force, and the camera device will be completely unlocked, unrestrained, and can be disassembled.

[0060] This utility model provides a concept and method for a small intelligent IP camera with ADAS and DMS. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
