Description

Technical Field

[0001] The utility model relates to the technical field of driving assistance, in particular to a driving assistance device. Background Art

[0002] Driving assistance systems include forward-facing ADAS (lane detection, collision detection, and pedestrian detection systems), rear-facing RVC (rearview camera system), and DMS (driver monitoring system), primarily used in logistics vehicles and ride-hailing services. The DMS (driver monitoring system) is based on machine vision and artificial intelligence technologies. It monitors and analyzes the driver's facial features, eye movements, head posture, and other information in real time to determine driver fatigue and attention, thereby ensuring driving safety. To monitor the driver's condition, the DMS camera's field of view must fully cover the driver and must be compatible with different vehicle models.

[0003] Conventional driving assistance devices utilize an angled cantilever. The DMS lens (straight head) is mounted on the cantilever via a circular clip. The DMS lens can be rotated to adjust its angle (within a range of approximately 30 degrees) and then screwed securely to the cantilever. The cantilever is connected to the main body of the driving assistance device via a cylinder. The cantilever can be rotated to adjust its angle (within a range of approximately 120 degrees) and then screwed securely to the main body of the driving assistance device. The DMS lens is connected to the main board of the driving assistance device via an external power cable for power and communication.

[0004] However, if the screws connecting the cantilever to the driver assistance device fall off, the cantilever could fall off the device, affecting the driver's use. Secondly, when installing the driver assistance device, different car models and drivers vary. Straight-lens DMS lenses are difficult to adjust, making it difficult to accurately capture the driver's status. Utility Model Content

[0034] Below with reference to accompanying drawing some embodiment of the present utility model is described:

[0035] like Figure 1-Figure 7 As shown, the present invention provides a driving assistance device, including a device body 1, a lens 2 and a cantilever 3; a first connecting portion 310 is provided on the lower side of the cantilever 3, a first limiting member 303 is fixedly mounted on the first connecting portion 310, a first limiting hole 101 is opened on the device body 1 for the first limiting member 303 to pass through, the first limiting member 303 includes a first cylinder and a second cylinder, the first cylinder is horizontally fixedly mounted on the first connecting portion, the second cylinder is coaxially fixedly mounted on a side of the first cylinder away from the first connecting portion, and the diameter of the second cylinder is larger than the diameter of the first cylinder, and the diameter of the first limiting hole 101 is larger than the first cylinder and smaller than the second cylinder;

[0036] A first arc-shaped stepped groove 305 with the first limiting member 303 as the center is formed on the first connecting portion 310. A first bolt 4 threadedly connected to the device body 1 is provided in the first arc-shaped stepped groove 305. The first bolt 4 is used to lock the cantilever 3 on the device body 1, and the lens 2 is fixedly mounted on the upper side of the cantilever 3.

[0037] The cantilever 3 can be fixedly mounted on the device body 1 by the first bolt 4. When the first bolt 4 loosens and falls off the device body 1, the second cylinder is still confined in the device body 1. Through the connection between the first cylinder and the cantilever 3, it can ensure that the cantilever 3 is always fixedly mounted on the device body 1.

[0038] There can be 1, 2 or 3 first arc-shaped stepped grooves 305, and each first arc-shaped stepped groove 305 matches the corresponding first bolt 4 and the first limiting hole 101. In order to ensure the stability of the connection between the cantilever 3 and the equipment body 1 and the convenience of installation, there are preferably two first arc-shaped stepped grooves 305 here, and the two first arc-shaped stepped grooves 305 are symmetrically arranged along the vertical center plane of the cantilever 3.

[0039] Further, if Figure 1 、 Figure 3 and Figure 5 As shown, a second connecting portion 311 is provided on the upper side of the cantilever 3, and a second limiting member 304 with the same shape as the first limiting member 303 is fixedly installed on the second connecting portion 311. A second limiting hole 201 for the second limiting member 304 to pass through is provided on the lens 2, and a second arc-shaped stepped groove 306 with the second limiting member 304 as the center is provided on the second connecting portion 311. A second bolt 5 threadedly connected to the lens 2 is provided in the second arc-shaped stepped groove 306, and the second bolt 5 is used to lock the lens 2 on the cantilever 3.

[0040] The way the lens 2 is installed on the cantilever 3 is the same as the way the cantilever 3 is installed on the device body 1. The device body 1 and the lens 2 in this device are both in the form of two parts that are snapped together. When producing this device, the first limiting member 303 and the second limiting member 304 on the cantilever 3 are respectively snapped into one half of the device body 1 and the lens 2, and then the other half of the device body 1 and the outer shell lens 2 of the lens 2 are snapped together and installed, so that the first limiting member 303 and the second limiting member 304 are respectively limited in the first limiting hole 101 and the second limiting hole 201, thereby ensuring that the lens 2 is always fixedly mounted on the cantilever 3, avoiding the possibility of falling, and improving the user experience.

[0041] To ensure the rotation angle of the lens 2, the second arc-shaped stepped groove 306 is preferably one. After the lens 2 is rotated to a suitable angle, the lens 2 is fixedly mounted on the cantilever 3 by the second bolt 5. The lens 2 is a DMS lens 2, which is a prior art and will not be described here.

[0042] Further, if Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, the cantilever (3) includes a mounting shell (301) and a fixing member (302), the fixing member (302) is embedded in and fixedly mounted in the mounting shell (301), the first limiting member (303) and the second limiting member (304) are both fixedly mounted on the fixing member (302), a gap for the power line to pass through is left between the fixing member (302) and the mounting shell (301), a limiting strip (3021) is fixedly mounted on the fixing member (302), the limiting strip (3021) is abutted against the inner wall of the mounting shell (301), and the first limiting member (303) and the second limiting member (304) are both provided with a connecting hole (309) connected to the gap.

[0043] Further, if Figure 1 As shown, a first scale 307 is provided on the side wall of the first arc-shaped stepped groove 305 , and a second scale 308 is provided on the side wall of the second arc-shaped stepped groove 306 .

[0044] The first scale 307 ranges from 0° to 120°, and the second scale 308 ranges from 0° to 200°. The first scale 307 and the second scale 308 facilitate adjustment of the installation angle of the cantilever 3 and the lens 2 by the operator, and also facilitate memorization of the current installation angle. If the cantilever 3 or the lens 2 is adjusted by another operator, the installation angle can be quickly restored.

[0045] Further, if Figure 5 、 Figure 6 and Figure 7 As shown, a gap is left between the fixing member 302 and the mounting shell 301 for the power line to pass through. A limit strip 3021 is fixedly installed on the side of the fixing member 302 close to the cantilever 3. The limit strip 3021 is abutted against the inner wall of the mounting shell 301. A connecting hole 309 communicating with the gap is provided on both the first limit member 303 and the second limit member 304.

[0046] The connection line between the device body 1 and the lens 2 is routed internally through the connection hole 309 and the gap, which reduces the need to connect external lines during installation. The operation is simple and the appearance of the device can be more beautiful and simple.

[0047] Further, if Figure 3 and Figure 4 As shown, the lens 2 includes a mounting portion 202 and a working portion 203 , the angle between the central axis of the working portion 203 and the extension line of the central axis of the mounting portion 202 is in the range of 10°-15°, and the second limiting hole 201 is provided on the side wall of the mounting portion 202 .

[0048] Through the above setting, the viewing angle of the lens 2 can cover more of the main driver, so that a more accurate driver status can be obtained. Here, the angle between the central axis of the working part 203 and the extension line of the central axis of the installation part 202 is 10°.

[0049] Further, if Figure 1 、 Figure 5 and Figure 7 As shown, the cantilever 3 is a straight cantilever.

[0050] Compared with being installed on a bent cantilever, when the lens 2 is installed on a straight cantilever, the convexity will be smaller, making the device more beautiful.
