Figure 1-Figure 12 The driver monitoring device 100 according to the embodiment of the present invention is described, comprising: a housing 10, a first circuit board 20 and a second circuit board 21. The driver monitoring device 100 has a first direction A, a second direction B and a third direction C.

[0046] Specifically, if Figure 1-Figure 5 As shown, the inner wall surface of the housing 10 includes a supporting surface 111 , the first circuit board 20 is disposed in the housing 10 , and the second circuit board 21 is stopped between the first circuit board 20 and the supporting surface 111 .

[0047] Combination Figure 1-Figure 5 The support surface 111 is a side surface of the inner wall of the housing 10 along the second direction B. The first circuit board 20 and the support surface 111 are arranged opposite to each other along the second direction B. The first circuit board 20 is fixedly connected to the housing 10 by a fastener. The second circuit board 21 is arranged parallel to the second direction B. The second circuit board 21 is located between the support surface 111 and the first circuit board 20. One end of the second circuit board 21 along the second direction B abuts against the support surface 111, and the other end of the second circuit board 21 along the second direction B abuts against the first circuit board 20.

[0048] According to the driver monitoring device 100 of the embodiment of the utility model, the arrangement of the second circuit board 21 abutting between the first circuit board 20 and the support surface 111 can optimize the layout of the internal structure of the driver monitoring device 100. The second circuit board 21 is fixedly installed inside the driver monitoring device 100 by abutting between the support surface 111 and the first circuit board 20, which can effectively improve the space utilization inside the driver monitoring device 100, simplify the installation structure 35 of the second circuit board 21, and is conducive to the miniaturization of the driver monitoring device 100, thereby improving the adaptability and practicality of the driver monitoring device 100.

[0049] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second circuit board 21 is perpendicular to the first circuit board 20. The first circuit board 20 is arranged inside the housing 10 parallel to the first direction A, and the second circuit board 21 is arranged parallel to the second direction B. The second circuit board 21 and the first circuit board 20 are distributed inside the housing 10 in a T-shaped structure, and the other end of the second circuit board 21 along the second direction B abuts against the middle of the first circuit board 20 along the first direction A. Therefore, the vertical distribution of the first circuit board 20 and the second circuit board 21 in the housing 10 is conducive to optimizing the internal layout of the housing 10 of the driver monitoring device 100, improving the space utilization rate inside the housing 10, and simplifying the installation structure 35 of the first circuit board 20 and the second circuit board 21 in the housing 10.

[0050] According to some embodiments of the present invention, Figure 1As shown, the first circuit board 20 is parallel to the support surface 111, and the second circuit board 21 abuts against a side surface of the first circuit board 20 adjacent to the support surface 111 in the thickness direction. The support surface 111 is arranged parallel to the first direction A, the first circuit board 20 and the support surface 111 are arranged opposite to each other along the second direction B, one end of the second circuit board 21 along the second direction B abuts against the support surface 111, and the other end of the second circuit board 21 along the second direction B abuts against a side surface of the first circuit board 20 adjacent to the support surface 111 along the second direction B. Thus, the position distribution of the first circuit board 20 and the second circuit board 21 in the housing 10 facilitates full use of the space in the housing 10 and optimizes the layout in the housing 10.

[0051] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, it also includes: an elastic member 24, which is arranged between the second circuit board 21 and the first circuit board 20. The elastic member 24 extends along the third direction C, and a side surface of the elastic member 24 along the second direction B is suitable for matching with the other end of the second circuit board 21 along the second direction B, and the other side surface of the elastic member 24 along the second direction B is suitable for abutting against a side surface of the first circuit board 20 adjacent to the supporting surface 111 along the second direction B, that is, the elastic member 24 is arranged between the first circuit board 20 and the second circuit board 21, and the elastic member 24 has a certain elasticity and can undergo a recoverable deformation.

[0052] Therefore, the elastic member 24 is arranged between the second circuit board 21 and the second circuit board 21 to play a certain protective role for the first circuit board 20 and the second circuit board 21, and the elastic member 24 can undergo a certain deformation, which is convenient for the first circuit board 20 to press the second circuit board 21 tightly against the support surface 111, and effectively eliminate the loose installation of the second circuit board 21 in the shell 10 caused by the tolerance of other components, so that the assembly of the second circuit board 21 in the shell 10 is more stable, the internal structural stability of the driver monitoring device 100 is enhanced, and the reliability of the driver monitoring device 100 is improved.

[0053] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, the elastic member 24 is formed with a first groove 241, and one end of the second circuit board 21 adjacent to the first circuit board 20 is matched with the first groove 241. The first groove 241 extends along the third direction C, and the first groove 241 is formed by a portion of a side surface of the elastic member 24 along the second direction B being recessed in a direction away from the second circuit board 21, and one end of the second circuit board 21 adjacent to the first circuit board 20 along the second direction B is matched in the first groove 241. Therefore, the first groove 241 formed on the elastic member 24 facilitates the matching of the elastic member 24 with the end of the second circuit board 21, so that the matching between the second circuit board 21 and the elastic member 24 is more secure, and the first groove 241 can play a certain role in limiting the end of the second circuit board 21 in the first direction A.

[0054] According to some embodiments of the utility model, the elastic member 24 is a rubber member or a foam member. The rubber member has the characteristics of high elasticity, low hardness, good softness and good air tightness. The rubber member has a low elastic modulus, large elongation deformation, recoverable deformation, and can maintain elasticity within a large temperature range. Foam has the characteristics of being elastic, light, fast pressure-sensitive fixation, easy to use, flexible, ultra-thin, and reliable performance. Therefore, the elastic member 24 is a rubber member or a foam member, which can effectively ensure the protective effect of the elastic member 24 and the first circuit board 20 and the second circuit board 21. The elasticity of the rubber member can also be used to fix the second circuit board 21 on the support surface 111, thereby improving the stability of the installation of the second circuit board 21.

[0055] According to some embodiments of the present invention, Figure 3 and Figure 4 As shown, positioning grooves 112 are respectively formed on two side walls of the housing 10 that are opposite to each other, and two sides of the second circuit board 21 are respectively matched in the two positioning grooves 112. Positioning grooves 112 are respectively formed on two side walls of the housing 10 that are opposite to each other along the third direction C. The positioning grooves 112 are formed by a portion of the side wall surface of the housing 10 along the third direction C being recessed in the direction away from the center of the housing 10 along the third direction C. The positioning grooves 112 extend along the second direction B. The two positioning grooves 112 are arranged opposite to each other along the third direction C, and the two positioning grooves 112 are respectively matched with two side edges of the second circuit board 21 along the third direction C.

[0056] Therefore, the positioning grooves 112 respectively formed on the two opposite side walls of the shell 10 are suitable for cooperating with the second circuit board 21. The two positioning grooves 112 can limit the second circuit board 21 in the third direction C and the first direction A, so that the second circuit board 21 is more firmly assembled in the shell 10, thereby enhancing the structural strength of the driver monitoring device 100.

[0057] According to some embodiments of the present invention, Figure 2-Figure 4As shown, the shell 10 includes a first shell 11, one side of the first shell 11 is open, and the inner wall surface of the other side of the first shell 11 is a supporting surface 111; the second circuit board 21 is installed in the first shell 11 through one side of the first shell 11, and the first circuit board 20 is located on one side of the first shell 11.

[0058] The first shell 11 is open on one side along the second direction B, and the inner wall surface of the other side of the first shell 11 along the second direction B is a supporting surface 111. Positioning grooves 112 are formed on the two side walls of the first shell 11 along the third direction C. The second circuit board 21 is installed into the first shell 11 from the open side of the first shell 11 along the second direction B.

[0059] Therefore, the support surface 111, the positioning groove 112 of the first shell 11 and the first circuit board 20 jointly limit the second circuit board 21 to fix the second circuit board 21. The first shell 11 can limit and protect the second circuit board 21. The setting of the support surface 111 and the positioning groove 112 can effectively simplify the installation structure 35 of the second circuit board 21 inside the driver monitoring device 100, which is conducive to the miniaturization of the driver monitoring device 100.

[0060] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the shell 10 also includes: a second shell 12 and a third shell 13, the second shell 12 is connected to the first shell 11, and the first circuit board 20 is arranged in the second shell 12; the third shell 13 is arranged on a side of the second shell 12 away from the first shell 11, and the cross-sectional area of ​​the first shell 11 along the distribution direction from the first shell 11 to the third shell 13 is less than or equal to the cross-sectional areas of the second shell 12 and the third shell 13.

[0061] The first circuit board 20 is fixedly connected to the second housing 12 by at least one fastener, and one side surface of the first circuit board 20 along the second direction B is opposite to the open side of the first housing 11, and the first circuit board 20 is arranged between the first housing 11 and the second housing 12. Along the second direction B, the third housing 13 is arranged on the side of the second housing 12 away from the first housing 11, and the cross-sectional area of ​​the first housing 11 is less than or equal to the cross-sectional area of ​​the third housing 13 and the second housing 12, and the housing 10 is a T-shaped structure as a whole. Therefore, the arrangement of the second housing 12 facilitates the fixed installation of the first circuit board 20, and the arrangement that the cross-sectional area of ​​the first housing 11 along the distribution direction from the first housing 11 to the third housing 13 is less than or equal to the cross-sectional area of ​​the second housing 12 and the third housing 13 is conducive to optimizing the overall structure of the driver monitoring device 100, which can improve the integration of the driver monitoring device 100, and is also convenient for the installation and heat dissipation of the driver monitoring device 100.

[0062] According to some embodiments of the present invention, Figure 2-Figure 4As shown, it also includes: a third circuit board 22, which is arranged between the second housing 12 and the third housing 13, and the third circuit board 22 is arranged in parallel with the first circuit board 20. The third circuit board 22 is arranged parallel to the first circuit board 20, and the third circuit board 22 is arranged between the second housing 12 and the third housing 13.

The third circuit board 22 is an LED light board, and the third circuit board 22 can emit infrared light. The first circuit board 20 is provided with an image sensor 23. After the infrared light is emitted from the third circuit board 22, it is reflected by an object and enters the image sensor 23 to form an image. Therefore, the second housing 12 and the third housing 13 are suitable for fixing and installing the third circuit board 22, and the third circuit board 22 is arranged in parallel with the first circuit board 20, which is conducive to improving the space utilization inside the housing 10. The parallel arrangement of the third circuit board 22 and the first circuit board 20 is conducive to ensuring that the infrared light emitted by the third circuit board 22 can be used to the maximum extent.

[0063] According to the second aspect of the present invention, the vehicle A-pillar is as follows: Figure 6 As shown, the vehicle A-pillar includes: a pillar body 30 and a driver monitoring device 100 . The driver monitoring device 100 is the driver monitoring device 100 according to the first embodiment of the utility model. The driver monitoring device 100 is detachably connected to the pillar body 30 .

[0064] Combination Fig.12 The driver monitoring device 100 is detachably fixed on the A-pillar of the vehicle. The driver monitoring device 100 is provided with structures such as a camera module and an IR fill light. The camera module, the first circuit board 20, the second circuit board 21 and the third circuit board 22 are electrically connected to perform data exchange and analysis processing. The driver monitoring device 100 has algorithm processing capabilities. The driver monitoring device 100 collects driver images through the IR fill light and the camera module. The fill light emits IR light, which is reflected by an object and then focused by the lens to form an image and then transmitted to the ISP and SOC. The SOC analyzes the driver's facial expression and posture in real time, and can determine whether the driver has dangerous driving behaviors such as fatigue driving and distracted driving through the built-in algorithm. If the driver has dangerous driving behaviors, the driver monitoring device 100 will feedback the driver's dangerous driving behaviors to the vehicle host through the CAN signal, and the vehicle host can remind the driver through a sound alarm, or adjust the temperature and air volume of the air conditioner to refresh the driver.

[0065] According to the vehicle A-pillar of the embodiment of the utility model, the driver monitoring device 100 has a simple structure and a small size, which can save space occupied by the vehicle A-pillar. The driver monitoring device 100 is simple to install, and the matching structure of the vehicle A-pillar and the driver monitoring device 100 is simple and easy to demold. The driver monitoring device 100 is detachably connected to the vehicle A-pillar, which can simplify the assembly of the driver monitoring device 100, facilitate the maintenance and replacement of the driver monitoring device 100, and is conducive to enhancing the practicality of the vehicle A-pillar and reducing maintenance costs.

There are multiple buckle structures 31, and the multiple buckle structures 31 are arranged at intervals along the circumference of the driver monitoring device 100 to fix the driver monitoring device 100 on the column body 30. The buckle structure 31 has the advantages of stable gap, convenient assembly, high reliability and low production cost.

[0067] Therefore, the driver monitoring device 100 is detachably connected to the column body 30 through the snap structure 31, which is beneficial to reducing the production cost of the vehicle A-pillar and the driver monitoring device 100, simplifying the connection structure, and also saving the internal space of the column body 30 and the driver monitoring device 100, thereby reducing the difficulty of loading and unloading the driver monitoring device 100.

[0068] According to some embodiments of the present invention, Figure 5-Figure 9 As shown, the buckle structure 31 includes: a buckle hole 321 and a buckle 33, the buckle hole 321 is formed on one of the driver monitoring device 100 and the column body 30; the buckle 33 is arranged on the other of the driver monitoring device 100 and the column body 30, and the buckle 33 is fitted in the buckle hole 321 to connect the driver monitoring device 100 to the column body 30.

[0069] In some embodiments, a card hole 321 is formed on the column body 30, a buckle 33 is formed on the shell 10 of the driver monitoring device 100, and the buckle 33 is formed on the two side surfaces of the second shell 12 of the driver monitoring device 100 along the third direction C.

[0070] Therefore, the connection between the driver monitoring device 100 and the column body 30 is achieved through the cooperation between the buckle 33 and the buckle hole 321. The cooperation between the buckle 33 and the buckle hole 321 can make the connection between the driver monitoring device 100 and the column body 30 more reliable and firm, and prevent the driver monitoring device 100 from falling off the column body 30.

[0071] According to some embodiments of the present invention, Figure 6 and Figure 7 As shown, a plurality of extension portions 32 are provided on the column body 30 at intervals, and free ends of the plurality of extension portions 32 are respectively formed with latch holes 321; at least one latch 33 is respectively provided on two opposite side walls of the housing 10 of the driver monitoring device 100, and the latch 33 fits in the corresponding latch hole 321.

The plurality of buckles 33 correspond to the plurality of extension parts 32 one by one, and the buckles 33 are embedded in the clamping hole 321.

[0073] Therefore, a card hole 321 is provided on the extension portion 32 to facilitate the cooperation between the card hole 321 and the card hole 321. The cooperation between multiple extension portions 32 and multiple card buckles 33 can enhance the connection strength between the driver monitoring device 100 and the column body 30. On the premise of ensuring the assembly strength of the driver monitoring device 100, the force applied to each card buckle structure 31 is reduced, thereby extending the service life of the card buckle structure 31.

[0074] According to some embodiments of the present invention, Figure 5 , Figure 8 and Fig. 9 As shown, at least one stop structure 34 is disposed on the column body 30 , and the housing 10 of the driver monitoring device 100 has a stop surface 14 , which abuts against the stop structure 34 .
